#5577: The warning stack is not maintained
-------------------------------------------------------+--------------------

Milestone:  To Be Determined                           |   Component:  None   
  Version:  Boost 1.46.1                               |    Severity:  Problem

 === Problem ===
 When "#include" is executed for the following file, the warning stack is
 destroyed.
 The cause forgets to write "#pragma warning(pop)" or is a misuse of
 "#pragma warning(default: warning-number-list)".

 File list
  * boost/spirit/home/classic/core/composite/composite.hpp
  * boost/spirit/home/classic/core/composite/actions.hpp
  * boost/archive/xml_wiarchive.hpp
  * boost/program_options/parsers.hpp
  * boost/program_options/variables_map.hpp
  * boost/test/utils/nullstream.hpp
  * boost/test/utils/iterator/ifstream_line_iterator.hpp

  === Impact ===
 When the VisualStudio user uses a specific header, a part of a necessary
 warning is not displayed.

  === Reproduction code ===
